AR wont eject

Post by neonnight34609 » Fri Jul 15, 2016 12:13 am

bought a new bolt and the round will not eject from it. i have taken it apart and inspected it. it seems as if the extractor is holding onto the round to tight for it to eject off. has anyone come across this? i have since bought a new bolt and have no issues with the newer one of the 2

Is your ejector on the old bolt working properly?

they are both new bolts. The newest one works perfect the one that came as an assembly with the bolt carrier is the problem bolt.

And yes I had that out 3 times checking it. Cleaned the pocket and spring all looked good with the ejector plenty of spring tension

Take out the bcg from the rifle. Remove the bolt from carrier. manually insert a round (preferably a spent shell but regular round will work as well) grabbing the extractor side with shell rim first and then compressing the ejector rod, does it get stuck or attempts to extract?

Does it happen to have an O-ring under the extractor? If so, remove it and try again.

it does have the O ring i didnt try to remove it but will do that next ! everything i have been reading on like says the o-ring around the spring is the better design. but now that you mention it, it might be to good of a design and thats whats making the extractor hang on to the round to tight

The oring is band-aid for an over-gassed gun or a weak extractor spring and can be the cause your problem. Who's bolt/bcg are you running? Most ar's should not need an oring to operate properly and it's a temporary fix for the most part, an extra tension spring is a better route to take if an oring were to be needed. Related, I've seen a couple times of a bolt not wanting to slip over the rim due to the excessive tension that the oring provided, removing it solved the issue.

I recently had a friend who's sons AR was suffering extraction issues. The extractor spring, plunger and O ring were fine so I opened up the extractor lip a few thousands and it;s run fine since.
